In our alphabetical series of posts about various aspects of vegetable gardening, I thought B might be for bugs in the Vegetable Garden. But not the bad ones… lets look at a double B – Beneficial Bugs!
Bad bugs get loads of press, so I thought by looking at the good bugs, it may give you some ideas on controlling those bad, nasty and destructive bugs that can seemingly devour a vegetable garden overnight!
Ladybugs

There are good ladybugs and bad lady bugs, so how do you know which is which? Well its all in the spots!
The 28 spot ladybug is bad, but before you go squashing it make sure that it is destructive, if your vegies aren’t under threat maybe leave it be. But if you find an 18 spot ladybug, you should be delighted, these are the good ones. They will happily munch away on thrips, aphids, grubs and a few other nasty bugs.
Not only that they are quite an attractive little bug to have hanging about your vegie garden. Kids love them!
Lacewing
These are a green bug with 4 clear wings hence their name lacewings. And its the hungry little larvae of the lacewings that are predators. They devour pests such as scales and mealybugs, aphids, moth eggs and smaller caterpillars. I read somewhere that they can eat approx 60 aphids in an hour, now that’s an appetite!.
Spiders
While you may sometimes despair when you get tangled up in a web in the garden and then do the crazy “I just ran into a spiderweb” dance. Spiders are your friends, they eat various bugs and while you need to be wary of them eg redbacks, white tails and funnel webs just to name a few… they can be particularly handy.
There are a number of other very handy bugs that can take out the nasty ones, these also include wasps (citrus gall wasp is great for citrus trees), some bugs such as the Damsel Bug, Predatory Shield bug and this one sounds good… the Assassin Bug!
So how do you get these beneficial insects into your garden?
Attract these beneficial insects into your garden by planting a few attractive plants such as sunflowers, daisy’s, borage, parsley, rosemary,coriander and native plants, just to name a few.
You may decide if your infestation is bad, to buy some beneficial bugs. There a number of suppliers in Australia that sell these beneficial insects and a couple that I have found that sell via the Internet are: Bugs for Bugs – www.bugsforbugs.com.au & IPM Technologies – http://www.ipmtechnologies.com.au
